Why smart leaders deliberately trip themselves up

It's all too easy for leaders to uncritically adopt suboptimal strategies simply because they can't think of a better option, says Chip Heath. To avoid that, bosses should set up a "mental trip wire" that, if tripped, requires them to re-evaluate their decisions. "Setting a mental trip wire is a way of establishing another decision point in the future, so that if we get into a bad situation we'll revisit it," Heath explains.
